nmail

2 120 8.0 C++

Terminal-based email client for Linux and macOS

Project mention: Outlook is Microsoft's new data collection service | news.ycombinator.com | 2024-01-11

I confirm the issue of delays/freezing of Claws-mail. I really liked the simple UI, but freezing too often, couldn't stand it. I had searched about it, I got some answers that's it's single threaded if I recall well.
Since you mentioned mutt and it's steep learning curve, I recommend you another TUI MTA/mail app. It's nmail (https://github.com/d99kris/nmail). Simple, Pine/Alpine like interface, has great features (for example, saving mails in sqlite - can be used offline). Also the developer is active and friendly, in case you find bugs or have any proposals for enhancements.

pboted

1 23 4.7 C++

Standalone C++ client for I2P/Bote (server-less encrypted KademliaDHT-based email protocol). (by PurpleBote)

Project mention: Is I2P bote still a thing? | /r/i2p | 2023-05-01

There is another Bote implementation named pboted, but a planned feature is "Sending email anonymously" so it does not do that at the moment? If someone would be able to clarify this, it would be greatly appreciated
